My P3600 blu ray with wireless dongle inserted sees the wireless access point and my network name: msb. Even get 2-3 bars for signal strength. But it won't connect to network and fails 2nd network test, ip address, etc. Security is off. Linksys Wireless g router.
The wireless dongle works ok if inserted in the tv ln52b750. (I can wirlessly access photos/vidoes on laptop.)
I am attempting to connect to netflix (via blu ray player), which gives an error that it can't connect to network.
